These technologies enable multidimensional content viewing and collaboration through cloud-based systems and in real-scale environments, resulting in higher levels of efficiency. The aim of this research is to offer an integrative approach that combines project management philosophies, systems, technologies, and tools. The sections containing the results of this study are as follows. (1) A concise review of the benefits of LC, BIM, and XR technologies in the AEC industry, including BIM-based visualization support for LC (Lean-BIM) and BIM visualization in XR (BIM-XR). This section also presents an overview of the most commonly used wearable XRs on the market. (2) The presentation of an LBX process flow diagram and an IDEF0 diagram for the LB...

Some of the major issues that construction companies face with projects are finding design and construction mistakes before implementation; understanding details, processes, change orders, and requests for information; and lack of collaboration among project stakeholders. This paper aims to address these gaps, using a project delivery method that incorporates early stakeholder engagement. It is organized as follows: first, to define the status of this research area, the paper provides a concise review of the most recent papers about BIM, Lean, MR, BIM-Lean, and BIM-MR technologies that have appeared in peer-reviewed journals and international conference proceedings. Second, to guide the architecture, engineering, and construction (AEC) industry, the paper presents a BIM/MRLean-based project delivery management model that is based on flowchart and integrated definition function modeling (IDEF0) language. Finally, the paper highlights the advantages and challenges of the system under discussion. This paper provides a roadmap for future efforts toward implementing a BIM/MR-Lean-based management system in all stages of the construction industry. Such a management system provides significant opportunities to improve the quality of planning, understanding, and also performance of construction projects.

Handling the complexity and uncertainty of construction projects, however, requires well-prepared architects and engineers. Architecture and civil engineering students are also expected to go through the proper training to be well-equipped for this challenge. VR has proved a helpful tool for architecture, engineering, and construction (AEC) education environments with the aim to leave a lasting impact on a student's learning and experience. The purpose of this paper is to provide a brief review of the most recent VR systems in the design and construction industry and the education environment. The paper also evaluates the use of VR in a two-pronged approach by conducting a comprehensive literature review and interviewing students in the Master of Project Management (MPM) program. This paper could provide a roadmap for future efforts to implement VR into the architectural and construction industry as well as the education environment.

Integration of BIM and VR technology can develop workflow efficiency through enhanced common understanding and prepare students in architecture and engineering programs to become leaders of the AEC industry. However, the current shortage of AEC professionals trained in BIM and VR is still a barrier to collaborative working practice in this industry. This paper reviews previous work on the BIM, VR, and BIM-into-VR in AEC education/training to bridge this gap. It also presents an advanced framework to clarify creating and using the BIM model into VR workflow in the AEC industry through the integrated definition function (IDEF0) model. The authors further evaluated the BIM-into-VR applications in literature and real-life by surveying students’ learning performance in terms of eight characteristics relevant t...

This investment includes the initial construction cost, repair and rehabilitation costs, and all maintenance costs. An ability to determine the whole life cost of a bridge will help agencies evaluate the asset value of existing bridges, make better decisions on the design and construction of new bridges, and choose methods and approaches for rehabilitating existing structures such that the lowest life cycle cost is achieved rather than the lowest initial cost. Toward this end the whole life costs of Chicago trunnion bascule bridges are analyzed and found to be less than five times the initial costs for life spans exceeding 100 years. It was also shown that timely maintenance, repair, and rehabilitation can lower the life cycle cost of a bridge.

Several recent studies have recognized the potential benefits of Life-Cycle Cost analysis and call for use of such analyses when making infrastructure investments, including investments in bridges. The Life-Cycle Cost of a bridge consists of the total investment throughout the life of the bridge. This includes the initial construction cost, repair and rehabilitation costs, and all maintenance costs. The ability to accurately determine the Life-Cycle Cost of a bridge will help agencies evaluate the asset value of existing bridges, make better decisions on the design and construction of new ones, and choose improved methods and approaches for rehabilitating existing structures. Research has shown that timely maintenance, repair, and rehabilitation can lower the Life-Cycle Cost of a bridge. However, this is a complex and nonlinear problem, and previous studies have failed to develop a satisfactory model. ...

ASCE has clearly supported this idea by adopting the master’s degree (or its equivalent) as the first professional degree. The means to acquire additional technical expertise has been addressed quite adequately by a variety of master’s degree programs at many universities throughout the country, but the challenge to impart the requisite managerial skills has not been satisfied very effectively. The latter is based on the premise that an MBA education is not ideal for managing large public and private projects which require managers with considerable technical expertise, as well as managerial skills. The Master of Project Management (MPM) program at Northwestern University has been established in response to this specific ...
